Benefits of technology

Enables users to confirm communication stability before shooting, preventing image loss by displaying the communication state, allowing for secure image transfer to the file server.

Problems solved by technology

However, in the digital camera disclosed in this document, the user cannot check before shooting (capturing) images whether communication between the digital camera and the file server can be normally established.
Thus, in the case where communication between the digital camera and the file server cannot be normally established, and the user shoots digital images, the shot digital images may not be stored on the file server.
For example, when a wireless LAN exists between the digital camera and the file server, the communication link between the two is likely to be unstable based on the location of the digital camera in relation to the wireless LAN's “hotspots”.
Thus, in many cases, communication between the digital camera and the file server cannot be normally established.

Embodiment Construction

[0015]Embodiments of the present invention will be described in detail below with reference to the drawings.

[0016]FIG. 1 is a block diagram showing the structure of a digital camera 10 that is a typical image capture device according to this embodiment of the present invention.

[0017]An image capturing unit 101 converts light beams received by an image sensing element (a CCD image sensor, a CMOS image sensor, or the like) to electrical signals when a shutter button is full-pressed, digitizes these electrical signals to generate digital images, and stores the generated digital images in a first buffer memory 102. When the shutter button remains full-pressed, the image capturing unit 101 continues capturing digital images until the first buffer memory 102 is full. The first buffer memory 102 has a capacity for storing a plurality of digital images.

[0018]An image processing unit 103 reads the digital images from the first buffer memory 102 and performs a developing process on these digi...

Abstract

An image capture device is capable of transmitting captured images to a file server on a computer network. The image capture device stores the state of the communication environment with the file server, transmits a signal, based on the stored communication settings, to the file server to determine the state of the communication environment with the file server, and determines, based on the results of transmitting the signal, the communication environment with the file server.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to image capture devices, for example, digital cameras and digital video cameras.[0003]2. Description of the Related Art[0004]Recently, many products in compliance with radio communication standards such as IEEE 802.11x (IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, and the like) and Bluetooth have been available, and wireless base stations called hot spots have been installed in, for example, street shops.[0005]In view of environments where wireless LAN technology described above is widely used, a digital camera that enables a user to shoot images without caring about the capacity of a recording medium by storing the captured images in a file server through a wireless LAN is proposed in, for example, Japanese Patent Laid-Open No. 2003-283900.[0006]However, in the digital camera disclosed in this document, the user cannot check before shooting (capturing) images whether communication between th...
